I don't know if it's a recent update that caused this or if I messed something up. I was working in a prefab where some of my icons are located. I saved the prefab as usual, but in-game, the icons seem to have changed color spaces?
Quick update: the only way I've found so far to work around this issue is to click on my image and select “Create Texture,” then assign the sRGB color space to the newly created .Vtex file. And the colors look fine! This makes me wonder if the automatically generated Vtex files might have an issue with color space assignment during generation ?
